APMT1604PDER Cross Reference
Equivalent APMT1604PDER inserts across 4 brands — Mitsubishi, Korloy, ZCC-CT, Dormer Pramet. Same ISO 1832 geometry class; grades, coatings and application windows differ by manufacturer. Treat equivalents as starting points and verify on a sample part: a cross-reference matches the geometry, not the process.
A general-purpose nose radius: a balance of edge strength and finish that suits most first-choice turning before you tune up for finishing or down for roughing.

Cross-reference a grade at its ISO position
Type any maker's grade (e.g. GC4325, AC820P, T9215) to see grades other brands publish at the same ISO application position. VERIFIED = multi-source consensus; 2+ CHARTS = placement confirmed by two or more manufacturer-published charts; SINGLE-SOURCE = one chart only. Comparable at ISO position — not identical performance. Verify on a sample part.
Frequently asked questions
What does APMT1604PDER mean?
APMT1604PDER is an ISO 1832 insert designation. It decodes as: A — shape = 85° parallelogram; P — clearance angle = relief angle 11°; M — tolerance = class M — molded, medium tolerance on inscribed circle and corner point (typically ±0.05–0.13 mm depending on size); T — type = fixing hole with countersink, chipbreaker on one face (single-sided positive insert); 16 — cutting edge length / IC = 16 mm nominal (inscribed circle / edge length class); 04 — thickness = insert thickness 4.76 mm; PDER — suffix = manufacturer geometry / edge configuration suffix (chipbreaker style, hand of cut).
What is APMT1604PDER used for?
APMT1604PDER is a milling insert. The brand-equivalents table on this page lists each maker's grade and its ISO application window (the P, M, K and similar ranges). Match the geometry first, then choose the grade for your material and operation, and verify on a sample part.
What is the equivalent of APMT1604PDER across brands?
APMT1604PDER is a shared ISO 1832 geometry, so Mitsubishi, Korloy, ZCC-CT, Dormer Pramet each offer it in their own grades and coatings. A cross-reference matches the geometry, not the process, so treat equivalents as starting points and verify on a sample part.
Is APMT1604PDER a positive insert?
APMT1604PDER has positive clearance, so it is a positive, single-sided insert: lower cutting forces, suited to finishing, small parts and low-rigidity setups.
Does this cross-reference favour specific brands?
No. Comparable grades appear here only because manufacturer-published comparison charts place them at the same ISO application position. No manufacturer pays for placement, nothing on this page is sponsored, and CuttingToolsAI sells no tools and earns no commission. Placements backed by a single chart are flagged as such, and every comparison ends the same way: verify on a sample part before switching.
